ABSTRACT
ObjectiveTo observe the effect of the enhanced external counterpulsation （EECP） combined with drug on social function and efficacy in patients with depressive episodes， so as to provide references for the treatment of depressive episodes. MethodsA total of 66 hospitalized patients who was in hospital at department of psychiatry of the Second Xiangya Hospital of Central South University， met the criteria of Diagnostic and Statistical Manual of Mental Disorders，fifth edition（DSM-5） diagnosis of depressive episode or bipolar disorder depressive episode from May 2019 to March 2020 were included by simple random sampling. The participants were divided into study group （n=36） and control group （n=30） according to the random number table method. Both groups received conventional drug treatment， and the study group recieved the EECP intervention at same time. The Depression symptoms and social function were assessed before and after treatment by using Hamilton Depression Scale-24 item （HAMD-24） and Sheehan Disability Scale （SDS）. Treatment efficacy of the two groups was compared. ResultsAfter the intervention， the HAMD-24 and SDS scores in both groups were lower than those before treatment， the differences were statistically significant （t=8.149， 5.791， 8.016， 3.488， P˂0.01）. And the SDS score of the study group was siginficantly lower than that of the control group （t=-3.008， P<0.05）. The total effective rate of treatment in the study group was higher than that of the control group， and the difference was statistically significant （90.63% vs. 63.33%， χ²=8.725， P˂0.05）. ConclusionEECP therapy combined with drug has better efficacy on the patients with depressive episodes， and it can improve social function effectively.
ABSTRACT
OBJECTIVES@#Major depressive disorder (MDD) patients with anhedonia tend to have a poor prognosis. The underlying imaging basis for anhedonia in MDD remains largely unknown. The relationship between nodal properties and anhedonia in MDD patients need to be further investigated. Herein, this study aims to explore differences of cerebral functional node characteristics in MDD patients with severe anhedonia (MDD-SA) and MDD patients with mild anhedonia (MDD-MA) before and after the antidepressant treatment.@*METHODS@#Ninety participants with current MDD were recruited in this study. 24-Item Hamilton Depression Scale (HAMD-24) and Snaith-Hamilton Pleasure Scale (SHAPS) were used to assess the severity of depression and anhedonia at baseline and the end of 6-months treatment. The MDD patients who scored above the 25th percentile on the SHAPS were assigned to an MDD-SA group (n=19), while those who scored below the 25th percentile were assigned to an MDD-MA group (n=18). All patients in the 2 groups received antidepressant treatment. Functional magnetic resonance imaging (fMRI) images of all the patients were collected at baseline and the end of 6-months treatment. Graph theory was applied to analyze the patients' cerebral functional nodal characteristics, which were measured by efficiency (ei) and degree (ki).@*RESULTS@#Repeated measures 2-factor ANCOVA showed significant main effects on group on the ei and ki values of left superior frontal gyrus (LSFG) (P=0.003 and P=0.008, respectively), and on the ei and ki values of left medial orbital-frontal gyrus (LMOFG) (P=0.004 and P=0.008, respectively). Compared with the MDD-MA group, the significantly higher ei and ki values of the LSFG (P=0.015 and P=0.021, respectively), and the significantly higher ei and ki values of the LMOFG (P=0.015 and P=0.037, respectively) were observed in the MDD-SA group at baseline. Meanwhile, higher SHAPS scores could result in higher ei and ki values of LSFG (P=0.019 and P=0.026, respectively), and higher ei value of LMOFG (P=0.040) at baseline; higher SHAPS scores could result in higher ei values of LSFG (P=0.049) at the end of 6-months treatment. The multiple linear regression analysis revealed that sex were negatively correlated with the ei and ki values of LSFG (r= -0.014, P=0.004; r=-1.153, P=0.001, respectively). The onset age of MDD was negatively correlated with the ki value of LSFG (r=-0.420, P=0.034) at the end of 6-months treatment. We also found that SHAPS scores at baseline were positively correlated with the HAMD-24 scores (r=0.387, P=0.022) at the end of 6-months treatment.@*CONCLUSIONS@#There are obvious differences in nodal properties between the MDD-SA and the MDD-MA patients, such as the high ei of LSFG in the MDD-SA patients, which may be associated with the severity of anhedonia. These nodal properties could be potential biomarkers for the prognosis of MDD. The increased ei and ki values in the LSFG of MDD-SA patients may underlie a compensatory mechanism or protective mechanism. The mechanism may be an important component of the pathological mechanism of MDD-SA. The poor prognosis in the MDD-SA patients suggests that anhedonia may predict a worse prognosis in MDD patients. Sex and onset age of MDD may affect the nodal properties of LSFG at baseline and the end of 6-months treatment.

Objective To examine the prevalence of obstructive sleep apnea (OSA) in patients with acute coronary syndrome (ACS),and to evaluate the relationship of OSA with inflammatory biomarkers in ACS patients.Methods Patients with ACS treated at Beijing Anzhen Hopital from June 2015 to May 2017 were enrolled.Subjects were evaluated for OSA by sleep study,and were divided into a normal-mild OSA group (Apnea Hypopnea Index,AHI ＜ 15 times/h) and a moderate-severe OSA group (AHI ≥ 15 times/h).Laboratory examination and sleep study were monitored to analyze the effects of OSA on biomarkers by LSD-t test,Mann-whitney U test,or Chi-square test.Correlation analysis was performed to analyze the association of OSA with high sensitivity C-reactive protein (hs-CRP) by Spearman correlation anaylsis.Results A cohort of 836 patients with ACS were enrolled including 408 patients in the normal-mild OSA group and 428 patients in the moderate-severe OSA group.The levels of leukocyte(x 109L) [7.78 (6.33,9.86) vs 7.29 (6.01,9.16),P=0.006],neutrophils(× 109L) [5.05 (3.84,7.23)vs 4.80 (3.74,6.66),P=0.044],monocytes(x 109L) [0.42 (0.33,0.54) vs 0.39 (0.31,0.51),P=0.033],hsCRP(mg/L) [3.18 (1.10,11.52) vs 1.78 (0.65,6.46),P＜0.01],fibrinogen(g/L) [3.17 (2.87,3.74) vs 2.97 (2.59,3.50),P=0.002],and uric acid(μmol/L) [360 (302,422) vs 341(283,407),P=0.006] in the moderatesevere OSA group were significant higher than those in the normal-mild OSA group.AHI (correlation coefficient=0.171,R2=0.020,P＜0.01),ODI (correlation coefficient =0.201,R2=0.027,P＜0.01),and TSaO2 ＜ 90％ (correlation coefficient =0.105,R2=0.005,P＜0.01) were positively correlated with hs-CRP;minimal SaO2 (correlation coefficient=-0.100,R2=0.001,P=0.008) and mean SaO2 (correlation coefficient =-0.127,R2=0.006,P＜0.01) were negatively correlated with hs-CRP.Conclusions For patients with ACS,the level of inflammatory markers in the moderate-severe OSA group is significantly higher than that in the normal-mild OSA group.Hs-CRP is significantly associated with the severity of OSA.Diagnosis and monitoring of OSA should be considered in ACS management in the future.
ABSTRACT
Objective@#To investigate the impact of moderate/severe obstructive sleep apnea (OSA) on the prognosis of acute myocardial infarction.@*Methods@#We prospectively selected patients with acute myocardial infarction (AMI) who were hospitalized at the Emergency Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. Patients who met the inclusion criteria were examined with portable sleep respiration monitoring. Patients were divided into moderate/severe OSA group (apnea-hypopnea index (AHI)≥15 beats/hour) and no/mild OSA group (AHI<15 beats/hour) according to sleep AHI. The incidence of major adverse cerebrovascular events (MACCE) after discharge was compared between the two groups, and the independent risk factors of MACCE were analyzed.@*Results@#A total of 432 patients were enrolled in this study, including 211 moderate/severe OSA patients (48.8%). Compared with no/mild OSA group,patients with moderate/severe OSA had higher body mass index ((27.17±3.22) kg/m2 vs. (25.55±3.44) kg/m2, t=-5.033,P<0.001), higher proportion of history of percutaneous coronary intervention (PCI) (18.5%(39/211) vs. 8.6%(19/221), χ2=9.076,P=0.003), and higher proportion of 3-vessel disease (31.3%(66/211) vs. 24.9%(55/221), χ2=10.196,P=0.017). The median follow-up time was 1.0 (0.7, 1.7) years. The incidence of MACCE in the moderate/severe OSA and no/mild group was 19.9%(42/211) and 11.3%(25/221), respectively. Kaplan-Meier analysis showed a higher cumulative risk of MACCE in patients with moderate/severe OSA (log-rank test,χ2=5.467, P=0.019). Multivariate Cox regression analysis showed that moderate/severe OSA (HR=1.915, 95%CI 1.016-3.611, P=0.045) and diabetes mellitus (HR=1.819, 95%CI 1.022-3.238, P=0.042) were independent risk factors for MACCE at 1 year post discharge in patients with AMI.@*Conclusions@#Nearly half of AMI patients are complicated with moderate/severe OSA in this patient cohort. Coronary artery disease is more severe in AMI patients complicating with moderate/severe OSA. Moderate/severe OSA is an independent risk factor for MACCE at 1 year after discharge in patients with AMI. Whether the prognosis of AMI can be improved by intervention of OSA remains to be investigated.@*Trial Registration@#Clinical Trial.gov, NCT03362385.
ABSTRACT
Objective@#To explore the association between hypothyroidism and sleep breathing disorders in patients with coronary heart disease (CHD).@*Methods@#A total of 784 patients with CHD were consecutively enrolled at the Emergency & Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. According to thyroid function test results, patients were divided into hypothyroidism group (79 cases) and non-hypothyroidism group (705 cases). All patients had undergone sleep monitoring. The sleep apnea status was compared between the two groups. Multivariate logistic regression and linear regression models were used to analyze the association between hypothyroidism and sleep breathing disorders in patients with CHD.@*Results@#The proportion of females, mean body weight and body mass index in the hypothyroidism group were higher than those in the non-hypothyroidism group [26.6% vs.16.2%, (78.6±11.6) kg vs. (75.7±12.0) kg, (27.7±3.2) kg/m2 vs. (26.6±3.5) kg/m2, all P<0.05]. Patients in hypothyroidism group had a decreased average oxygen saturation (SaO2) compared with patients in non-hypothyroidism group [ (93.2±2.9) % vs. (93.9±2.0) %, P=0.030]. In addition, events of hypoventilation in hypothyroidism group were significantly higher than those in non-hypothyroidism group[92.5 (45.8, 758.3) times vs. 68.0 (33.0, 125.0) times, P=0.013]. There were no significant differences in apnea hypopnea index, diagnosis of obstructive sleep apnea and other sleep breathing parameters between the two groups (P>0.05). A multiple linear regression analysis found that in patients with CHD, the correlation between hypothyroidism and average sleep SaO2 was significant (β=-0.508, 95%CI -0.989--0.026, P=0.039).@*Conclusions@#CHD patients with hypothyroidism had a lower sleep average SaO2, and a higher sleep hypopnea events. There is a correlation between hypothyroidism and sleep hypoxia in patients with CHD.@*Clinical trial registration@#clinicalTrials.gov, NCT03362385.
ABSTRACT
As a widely recognized public health problem as well as prevalent and challenging to modern society, chronic insomnia is involved in wide brain areas (such as prefrontal cortex, anterior cingulate cortex, amygdala, hippocampus, and thalamus) and emotion-cognition neuro-circuit. It is closely related to the conditioned hyperarousal and the increased information process and/or the impaired inhibitory ability to withdraw from awaking state. Thus, some specific abnormal mode may exist in the emotion-cognition circuit, which is associated with abnormal cognition load, such as repeated retrieval/intrusion of aversive memories during night. Studies through the combination of multiple techniques including psychology, electrophysiology and neuroimaging methods are needed to further enhance the understanding of chronic insomnia.

Conditioned fear and its abnormal extinction are involved in the psychopathology of anxiety disorders, such as posttraumatic stress disorder (PTSD). Cognitive enhancing agents have been demonstrated to alter fear extinction in many animal research literatures. The present review has examined the pharmacological role of gamma-aminobutyric acid (GABA), glutamatergic, cholinergic, adrenergic, dopaminergic, and cannabinoid as well as compounds able to alter the epigenetic and neurotrophic mechanism in fear extinction, highlighting great hope for the future treatment of anxiety disorders with new agents based on the fear extinction.
